I'd like to be able to test a function with a tuple from a set of fringe cases and normal values. For example, in testing a function that returns true when given three lengths that form a valid triangle, I'd have specific cases, negative numbers, small numbers, large numbers, values close-to being overflowed, etcetera. Then generating co...
Getting back into a bit more .NET after a few-years of not using it full-time, and wondering what the good unit testing packages are these days. I'm familiar with NUnit (a few years ago), and have played briefly around with IronRuby, with the goal of getting something like rspec going, but don't know much beyond that. I realise I could...
Looking for books or other references that discuss actually "how" to write a code coverage tool in Java; some of the various techniques or tricks - source vs. byte code instrumentation. This is for a scripting language that generates java byte code under the hood. ...
I'm looking to add a testing suite to my application, however I can't move to the newer testing frameworks for .NET 3.5. Does anyone have a suggestion about good testing frameworks to use?...
I'm working on a project where I'm coding in C in a UNIX environment. I've been using the lint tool to check my source code. Lint has been around a long time (since 1979), can anyone suggest a more recent code analysis tool I could use ? Preferably a tool that is free....
Does anyone have some good hints for writing test code for database-backend development where there is a heavy dependency on state? Specifically, I want to write tests for code that retrieve records from the database, but the answers will depend on the data in the database (which may change over time). Do people usually make a separate...
I'm having trouble figuring out how to get the testing framework set up and usable in Visual Studio 2008 for C++ presumably with the built-in unit testing suite. Any links or tutorials would be appreciated. ...
Lots of people talk about writing tests for their code before they start writing their code. This practice is generally known as Test Driven Development or TDD for short. What benefits do I gain from writing software this way? How do I get started with this practice?...
Many people use Mock Objects when they are writing unit tests. What is a Mock Object? Why would I ever need one? Do I need a Mock Object Framework?...
I was working with quality yesterday doing some formal testing. In their procedure they were verifying all files on the test machine were pulled from the release. The way they were verifying these files were the same was by checking the size and the date/time stamp windows put on them in explorer. These happened to be off for another ...
At work we are currently still using Junit3 to run our tests. We have been considering switching over to Junit4 for new tests being written but I have been keeping an eye on TestNG for a while now. What experiences have you all had with either Junit4 or TestNG and which seems to work better for very large numbers of tests. Having flexibi...
We have a junior programmer that simply doesn't write enough tests. I have to nag him every two hours, "have you written tests?" We've tried: Showing that the design becomes simpler Showing it prevents defects Making it an ego thing saying only bad programmers don't This weekend 2 team members had to come to work because his code had a...
At my work we are running a group of tests that consist of about 3,000 separate test cases. Previously we were running this entire test suite on one machine, which took about 24-72 hours to complete the entire test run. We now have created our own system for grouping and distributing the tests among about three separate machines and the ...
I'm getting into more of a TDD workflow, and have a mix of MVC and asp.net Web Forms apps. MOQ is recommended for MVC. I've used Rhino for Web Forms. Does anyone have a best practice for having 1 framework mock for both? ...
What are all the types of software testing that you can put in front of the word "Testing"? Here are some examples: Unit Testing Functional Testing Integration Testing Performance Testing Stress and Volume Testing White Box Testing Black Box Testing User Testing Automated Testing Regression Testing Let's see if we can come up with g...
are you hiring employees just for testing or is it done by your developers? if you hire them, what are your experiences? what is the ratio of them to your developers? what kind of testers do you hire? do you use college grads or do your testers are masters and as good as your developers? do they make a huge difference for you and in ...
What tools are useful for automating clicking through a windows form application? Is this even useful? I see the testers at my company doing this a great deal and it seems like a waste of time. ...
Let's say we have a simple function defined in a pseudo language. List<Numbers> SortNumbers(List<Numbers> unsorted, bool ascending); We pass in an unsorted list of numbers and a boolean specifying ascending or descending sort order. In return, we get a sorted list of numbers. In my experience, some people are better at capturing boun...
In my limited experience with them executable requirements (i.e. specifying all requirements as broken automated tests) have proven to be amazingly successful. I've worked on one project in which we placed a heavy emphasis on creating high-level automated tests which exercised all the functionality of a given use case/user story. It wa...
While trying to advocate more developer testing, I find the argument "Isn't that QA's job?" is used a lot. In my mind, it doesn't make sense to give the QA team all testing responsibilities, but at the same time Spolsky and others say you shouldn't be using the $100/hr developers to do something a $30/hr tester could be doing. What are...
